What is the importance of Insurance?

Insurance benefits society by allowing individuals to share the risks faced by many people. But it also serves many other important economic and societal functions. Because insurance is available and affordable, banks can make loans with the assurance that the loan’s collateral (property that can be taken as payment if a loan goes unpaid) is covered against damage. This increased availability of credit helps people buy homes and cars. Insurance also provides the capital that communities need to quickly rebuild and recover economically from natural disasters, such as tornadoes or hurricanes.

Insurance itself has become a significant economic force in most industrialized countries. Employers buy insurance to cover their employees against work-related injuries and health problems. Businesses also insure their property, including technology used in production, against damage and theft. Because it makes business operations safer, insurance encourages businesses to make economic transactions, which benefits the economies of countries. In addition, millions of people work for insurance companies and related businesses. In 1996 more than 2.4 million people worked in the insurance industry in the United States and Canada.

Insurance companies perform a type of monetary redistribution—they collect premiums and eventually redistribute that money as payments. Depending on the type of insurance, redistribution can take anywhere from a few months to many decades. Because of this delay between collecting and paying out funds, insurance companies invest their funds to bring in extra revenues. Such investments help businesses and governments finance their operations, and profits from those investments support the operations of insurance companies. With these investment earnings, insurance companies can keep rates much lower than would otherwise be possible.

Not all effects of insurance are positive ones. The possibility of earning insurance payments motivates some people to attempt to cause damage or losses. Without the possibility of collecting insurance benefits, for instance, no one would think of arson, the willful destruction of property by fire, as a potential source of money.
